Siemens Sinumerik DNC

Hello,

I have Boehringer VDF - 560 DUS with Siemens Sinumerik 805. This model has only multifix. I wish to add 8 - position tool turret. In my country its very hard to find a proffesional that could add this to my Siemens controller, and as i was told it would cost me a lot of money, not to mention tool turret price.

At this moment i have not much experience with upgrading CNC machines, but i was wondering, MAYBE i could use DNC software (dont know which one) to drip feed. As far as i know turret start changing tool when it gets signal from controller. So Thats my question : Maybe there is DNC software, that could send signal directly to turret instead of Siemens sinumerik? In this way, i could change tools by-passing Siemens controller?
